Re: [photo-3d] hyperstereo of lightening

["Hershel Saylor" <saylor@xxxxxxx>]

If it were my project, I would do it via radio control.
By using RC servos connected to shutter release
cables, you could trigger them together.

I recall some really good lightning shots that I saw a
few years back.  The photographer described how
the shot were taken.  When ready to shoot, he
covered the lens with a black piece of cardboard
and then opened the shutter.  He would then uncover
the lens until he had what he thought was enough
flashes then cover it and close the shutter.

I didn't understand why he chose this method, but his
shots were incredible!!  I have tried to take lightning shots
several times over the years and have nothing to show
for my labor.
